Aberrant gene silencing is highly associated with altered cell cycle regulation during carcinogenesis. In particular, silencing of the CDKN2A tumor suppressor gene, which encodes the p16INK4a protein, has a causal link with several different types of cancers. The p16INK4a protein plays an executional role in cell cycle and senescence through the regulation of the cyclin-dependent kinase (CDK

CDKN2A is the second most frequently inactivated tumour suppressor gene in cancer 9, 11 and its inactivation is achieved in the majority of cases via homozygous deletion or promoter hypermethylation 11. Gene name: CDKN2A (HGNC Symbol) Synonyms: ARF, CDK4I, CDKN2, CMM2, INK4, INK4a, MLM, MTS1, p14, p14ARF, p16, p16INK4a, p19, p19Arf: Description: Cyclin dependent kinase inhibitor 2A (HGNC Symbol) Chromosome: 9: Cytoband: p21.3: Chromosome location (bp) 21967753 - 21995301: Number of transcripts i CDKN2A is one of the most studied tumor suppressor genes. It encodes the p16-INK4a protein that plays a critical role in the cell cycle progression, differentiation, senescence, and apoptosis. Mutations in CDKN2A or dysregulation of its functional activity are frequently associated with various types of human cancer. As a cyclin-dependent kinase inhibitor, p16-INK4a forms a complex with cyclin The CDKN2A gene encodes proteins that regulate 2 critical cell cycle regulatory pathways, the p53 (TP53; 191170) pathway and the RB1 pathway.Through the use of shared coding regions and alternative reading frames, the CDKN2A gene produces 2 major proteins: p16(INK4), which is a cyclin-dependent kinase inhibitor, and p14(ARF), which binds the p53-stabilizing protein MDM2 (Robertson and Jones Young et al., 2014, Loss of CDKN2A expression is a frequent event in primary invasive melanoma and correlates with sensitivity to the CDK4/6 inhibitor PD0332991 in melanoma cell lines., Pigment Cell Melanoma Res CDKN2A is a tumor suppressor gene comprised of 4 exons (1a, 1b, 2, and 3) that encode two tumor suppressor proteins, p16 (1a, 2, and 3) and p14 (exons 1b, 2, and 3), via differential splicing and alternative reading frames (PMID: 26488006). p14 is a stabilizer of the tumor suppressor protein p53, and p16 promotes the arrest of the cell cycle in the G1 phase by inhibiting CDK4-mediated phosphorylation of the RB1 protein (PMID: 26488006, NCBI Gene. 2017-11-06 · Background Multiple Myeloma is a cancer of plasma cells associated with significantly reduced survival.

CDKN2A negative indicates a lack of the CDKN2A gene, mRNA, and/or protein.

The CDKN2A gene provides instructions for making several proteins. The most well-studied are the p16(INK4A) and the p14(ARF) proteins. Both function as tumor suppressors, which means they keep cells from growing and dividing too rapidly or in an uncontrolled way.

The C DK N 2 A g ene codes for two different The CDKN2A gene located at 9p21 encodes two proteins, p16 INK4a and p19 ARF (p14 in human; refs. 20, 21 ). The p16 INK4a protein inhibits the CDK4–6 kinases, maintaining the Rb protein in an unphosphorylated, growth-suppressive state, arresting the cell cycle ( 20, 22 ).

This molecular alteration has been associated with enhanced tumorigenesis and poor prognosis in many other tumor types, such as melanoma [ 7 ], ovarian cancer [ 8 ], bladder cancer [ 9] and sarcoma [ 10 ]. 8 timmar sedan · Describing evolutionary conserved physiological or molecular patterns, which can reliably mark the age of both model organisms and humans or predict the onset of age-related pathologies has become a priority in aging research. The age-related gene-expression changes of the Cyclin Dependent Kinase Inhibitor 2A (CDKN2A) gene have been well-documented in humans and rodents.

Direct sequencing of the amplified CDKN2A gene showed no somatic mutations in the 17 tumors examined. The authors concluded that enhanced expression, rather than inactivation of the CDKN2A gene, may be involved in the early stages of the pathogenesis of primary colorectal carcinomas.
